Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
As shown in Figure 1, Figure 2, Figure 3 shows, diversion tunnel working tunnel is used as ecology for the reconstruction structure in water hole, including diversion tunnel 1
With the working tunnel that 1 side of diversion tunnel is arranged in, the working tunnel is divided into working tunnel 2 and lower working tunnel 3, wherein on
The entrance of working tunnel 2 is connected to river, and outlet is connected to diversion tunnel 1, the entrance of lower working tunnel 3 and upper 2 phase of working tunnel
Even, outlet is connected to diversion tunnel 1, and one end that the upper working tunnel 2 is connected with diversion tunnel 1 is equipped with gate 21,21 upstream of gate
Side is equipped with arc-shaped door lock chamber 25, and the junction of the lower working tunnel 3 and diversion tunnel 1 is equipped with closure plug 31, the upper construction
Branch hole 2 and the junction of lower working tunnel 3 are equipped with connection plug 32.After the completion of structure of modification construction, it's the water phase pasts diversion tunnel, can
Upper working tunnel 2 is blocked using gate 21, lower working tunnel 3 is blocked using plug 31 is blocked；In diversion tunnel 1
Lower lock water storage phase, dismountable gate 21 are controlled using arc-shaped door lock chamber 25, make upstream river water along upper working tunnel 2 into
Enter diversion tunnel 1, then flow to downstream and form ecological water supply, eliminates and reset an ecology for the engineering in water hole, have good
Economic benefit, the duration is greatly shortened.The specific structure of arc-shaped door lock chamber 25 is convenient for as shown in figure 5, its top is open type
Installation and adjusting arc-shaped door lock chamber 25.
Be arranged connection plug 32 purpose be, if not connecting plug 32, when carrying out ecological water overcurrent, although under apply
The outlet end in work branch hole 3, which has passed through, to be blocked plug 31 and seals, water flow can not overcurrent, but in river water full of after lower working tunnel 3,
Newly into water flow still can form impact turbulent in upper working tunnel 2 and the junction of lower working tunnel 3, it is raw not to be able to satisfy downstream
State water supply requirement, and since lower 3 position of working tunnel is lower, it is subsequent also to need to pull water out, it is more troublesome, increases without recruitment
Journey.And after being provided with connection plug 32, water flow directly from upper 2 overcurrent of working tunnel, reduces path, also just reduces and apply
The engineerings such as reconstruction, the reinforcing in work branch hole.
The construction method of the reconstruction structure, comprising the following steps:
A, the access tunnel constructed in diversion tunnel construction time, the above working tunnel 2 and lower working tunnel 3 as diversion tunnel 1, it is complete
Structure after is as shown in Figure 1；
B, after the completion of diversion tunnel construction, in the outlet end of lower working tunnel 3, setting blocks plug 31, in upper working tunnel 2
Outlet end setting gate 21 and with arc-shaped door lock chamber 25, structure after the completion is as shown in Figure 2；
C, the dam construction phase first blocks upper working tunnel 2 with gate 21, using 1 overcurrent river water of diversion tunnel, then builds big
Dam cofferdam carries out dam construction；
D, after the completion of dam construction, the 1 lower lock water storage phase of diversion tunnel first removes the gate 21 in upper working tunnel 2, then leads to
Overregulate in working tunnel 2 arc-shaped door lock chamber 25 make ecology supply water through upper working tunnel 2 to diversion tunnel 1 carry out overcurrent,
Reservoir level can be risen simultaneously and be controlled, as shown in Figure 3；
E, after dam reaches water storage requirement, 2 arc-shaped door lock chamber 25 of working tunnel stops supplying water in closing, then in upper construction
Permanent plug 24 is set between the arc-shaped door lock chamber 25 and diversion tunnel 1 in branch hole 2, and reconstruction is completed, such as Fig. 4 of structure after the completion institute
Show.
By being transformed to traditional working tunnel, so that working tunnel different times have different functions, water conservancy diversion
The construction time in hole 1, the access tunnel that working tunnel is constructed as diversion tunnel；The construction time of dam blocks 31 He of plug by setting
Gate 21 ensure that the normal diversion function of diversion tunnel 1；The dam water storage phase preferably resolves lock under high earth and rockfill dam diversion tunnel
The water storage phase does not stop, and meets the requirement of downstream ecology flow, while it is uppity to solve high earth and rockfill dam reservoir level rising
Problem.And the characteristics of entire improvement project is gradually to be transformed, and makes full use of different times high rock fill dam construction water conservancy diversion, it is subsequent to change
It makes and is carried out on the basis of previous transformation, can greatly alleviate the duration pressure of construction in later period in this way, shorten critical circuits
Construction period.
Since the trunk roads of working tunnel are generally parallel with diversion tunnel 1, then need to be arranged when needing and being connected to diversion tunnel 1
Corner is turned to diversion tunnel 1, and right-angled bend is usually used in currently existing scheme, but in order to reduce water when subsequent overcurrent ecology supplies water
The impact to working tunnel is flowed, is connected by arc-shaped transition section 22 with diversion tunnel 1 in the outlet end of the upper working tunnel 2.Into
One step, in order to reach most smooth overcurrent, the radius of the arc-shaped transition section 22 should be greater than the hole diameter of 5 times of upper working tunnels 2,
Corner is less than 60 °.
As shown in figure 3, the entrance of the lower working tunnel 3 is connected with the arc-shaped transition section 22 of upper working tunnel 2, in order to
22 phase of arc-shaped transition section of upper working tunnel 2 is agreed with, and sets the upstream face of the connection plug 32 to and upper working tunnel 2
The cambered surface that arc-shaped transition section 22 matches.
Punching is formed to the outlet of upper working tunnel 2 when entering diversion tunnel 1 from upper working tunnel 2 in order to avoid ecological water flow
Brush, is equipped with liner structure section 23 in the outlet end of the upper working tunnel 2, and the gate 21 and the setting of arc-shaped door lock chamber 25 exist
In liner structure section 23, the liner structure section 23 is equipped with gradual transition section far from one end of diversion tunnel 1.The liner structure section 23
Simultaneously construction basis can be provided for the subsequent permanent plug 24 of setting.
In view of entire duration situation, to reconstructing preferably during carrying out water using diversion tunnel 1 for upper working tunnel 2
Dry season carries out, specifically, cofferdam is arranged in the entrance in upper working tunnel 2, then reconstructs to upper working tunnel 2, including
In junction setting connection plug 32, arc-shaped door lock chamber 25 and the liner structure section 23 of upper working tunnel 2 and lower working tunnel 3
Transition construction so that upper working tunnel meet ecology supply water overcurrent requirement.
The reconstruction structure of the application takes full advantage of the design feature of working tunnel and water conservancy diversion, is made by transformation gradually whole
A engineering not only meets ecological water supply requirement, has saved cost and duration, even more plays different works in the different construction stages
With, or even solve high earth and rockfill dam reservoir level and rise uppity problem, there is good practicability and application prospect, be
Similar engineering provides good reference.
